I think that Country C would be suitable for Alison's retirement as the population is fairly high and should be able to make a lot of friends in the country. I also think it would be suitable for Alison as the percentage of population living in Urban areas is 74% which is almost all the population.
I think that Country F would be suitable for Charlie, because the population is fairly high but there is a low percentage of the population living in urban areas. Also, compared to the other countries, there isn't a lot of land that is uninhabitable.
In conclusion, I think Country F will be good for Charlie because there won’t be very meny people and he or she won’t feel very overcrowded, as there will be lots of space and not many people. I also think Country C will be good for Alison because she said that she would like to live somewhere where there will be lots of activity and can make some new friends. i think that she would be able to make lots of new friends as there is a lot of people living there.
